I made your quality mod on my Gforce 2 GTS. It worked just great. I was careful to check for shorts with strong magnifyer and needle before I rienstalled it. The image detail was significantly improved. I have now upgraded to a 4600, and the board is mechanicaly different. It's image quality in both 2d and especialy 3d is much better. I want to do your mod on it but would love to see some info first. I went over your mod on the GF2 several times before I made the change to be certain of what I was doing. my caution payed off. I am gratefull for your work on this because I am an image geek. Thank you, look forward to any help.
